permitting C of steel in a horizontal position under the conditions
prevailing during continuous production of steel, with cutting

A classification of steels of various grades isgiven in terms of
cutability (relative to cold C), and nomographs of the major
parameters of the process of C of a holt:,billet:~to' a depth of
100-300 mm are plotted. The major peculiarities of C of a.

percent,below,the normal; 3) in C of steel 150-200 mm thick, : the dis-
tance between the orifice and the metal being cut should'ibe 70-100 mm;
4) horizontal C of cold metal is possible under the same conditions as ordin-
ary C in the lowered position, on condition that the unit, flow of 02 per unit

crease in the temperature of the metal to 10000C as compared'to the C of
metal having a temperature of 300-5000C ; 6) an increase in~the temperature
of metal prior to C impairs somewhat the quality of the'~ surface of the cut and
increases the amount of adhering slag and also fusion.ofAhe edges, but 'on the
other hand it increases the stability of the process.; 7) to, assure. stability of;'
the process of "hot" C, it is necessary to increaseXhe pbwei. ofJhe pre-heat

The -4,, (uRns-4) Installation for Oxygen-Flux Cutting',of Stainless Steel
operational features are described. The use of externai~ fluxifeed to the.cutter,
made it possible to simplify the design of the flux feeder and to~employ 6utters
used in conventional oxygen cutting of low-carbon steel.;,;.Mor6oier, the use of a
cyclone flux feeding device ensured the accurate dosage*6f small amounts of powders
supplied to the area of cutting. Speeds of cutting stainless's,teel, attained
on the "URMS-11" machine exceed those of the URKhS-3 machine,bi~a factor of 1.8-
2.3; they may be compared to speeds of cutting low-carb'On.steel of the:'swe
thickness. The higher speeds are achieved by increased oxygenconsumption without
a higher flux consumption, by a smaller width of the oxiaatio'n r~eaction;front,
and by the intensified fluxing of oxides.~,The specific'flux consumptionof the
URKhS_4 machine was by 2-4 times lower than that of the.'VRXhS_3,machine,due to
a finer grain size of the flux (less~than 0.15 mm) and.'a'~bett~Pr.distribil~ion~of
the flux over the cutting area. As a result the cost ofimaterial per 1~running
meter of cut was reduced by a factor of 1.3-2.- The frarl _~" (VIM)'iron powder of
the following composition is recommended for use-on the!.URKhS_2r'machine:- 94_wq6%

TEXT: The selective oxidation of the elements in the rimctlon pace of oxygen
cutting of carbon steel modifies the composition of the metal along the edge 6f the
cut. It may be of interest to introduce alloying elements into the cutting zone of
austenitic and serniferritic steels to control the resulting change's. Metallographic
and chemical studies were performed on specimens on which O-fliix cutting-had:
been done on cold metal and on metal heated to 140-Z500C.~ The flux powde-- con-
sisted of BK (VK) iron containing (in To). 0.2 C, 0.5 Mn, .6.5 Si,' and 95.5 Fetotal-
The chemical compositions of the steels cut and the proceAural.culting parameters
employed are tabulated. Structural changes were observed in the cutting zone,
comprising an overheated structure directly adjacent to the cut "and. a transition al
structure between the overheated structure and the parenti metal. A tabulation'
shows that the depth of the zone of the thermal effect depen'ds oni,the proc dur'.1

parameters, but the depth of the overheat zone depends on the chemistry a~nd the

overheat region evinced a weakly-etchable band (illustrated by photo) in which pro-
longed electroetching in 107o oxalic acid revealed a dendritk structure character-
istic of cast metal. In extremely high-Cr steels the overheated area has a finely
acicular structure (photo). The HV hardness of the martensitic la'~er next to the
cut edge is 400, increases to 630 at 1.5mm. depth, decreases' to 3 20 at 5 mm: dep th
(probably owing to self-anneal), and transits into troostite. Spectrum analysis re-
veals a significant alteration of the alloying elements at and.nearlthe cut edge (to
0.3 mm depth), depending primarily on the degree of preheating of the metal prior
to O-flux cutting. Analyses made on steels X17 (Khl7) and lX11 (lKhl3) are
shown. Cr, Mn, and Si burn out readily; in Mark- 18-8 steels the upper edge is
enriched with Ni, the concentration of which diminishes as the cutting jet perietra-
tes the depth of the metal. The Ni concentration in the exit zone of the jet amounts
to about 55-9516 of that in the parent metal. Preheating facilitate s:.the, burn-out of
alloying elements. The resulting change in composition red uces the stability of the
austenite in NiCr steels, since the martensite-transformati6n temp Ierature is raised
thereby. The causes engendering the change in chemical composition are sought.
The iron powder introduced burns up in the 0 stream and raises the temperature,,
whereupon: (1) The high solubility of the alloying elements facilitates their.trans-
ition from the cut edge into the slag and back; also, the alloying elements in the';
~s wit higher tem
perature,
steel transit from regions with lower temperature to region h

where their solubility is greater. This conclusion was substantiate'd.by cutting
two packeted plates conjointly, one of lKhl8N9T and one of CT.3 (St.3). The low-
C steel underwent Ni enrichment at the cutting edge. This phenomenon can only be
explained by Ni diffusion from the slag. (Z) The abrasive action of the fast-moving
flux particles and the removal thereby of the refractory oxide formed on the con-:
tact surface. (3) The mechanical mixing in the. cutting zone of the parent metal and
the powder with various concentrations of alloying elements and their'strong oxida-
tion due to the high 0 excess. Speedier cutting reduces the time of c ntact of Ithe
0
liquid slag with the cutting edge and minimizes diffusional exchanges.' An interpre!,
tation of the resulting process as occurring iha two-phase system appears justified
by experimental evidence. In view of the impLirment of the ph sic' chemical
y 0-
characteristics of the metal near the cut edge it 1s recommended that'd 0. 5 mm 6f
the material near the edge be removed by grinding. There are - 9 fi I uies * an&

TEX.T: The authors propose a method of calibrating primary transducers for
measuring high-intensity direct currents by the nuclear magfi~tic resonance method:.
They use the comparison of measurement units designed for various':ranges of
currents to be measured. The advantage of the method consists in,the fact that
it does not require the exact measurement of the geometric dimensions of the
transducers and, consequently, their precise treatment'.

magnetic fields and the great variety of circumstances under which magnetic induction measuralt;'

from the search coil during its removal from the inhomogeneous field being measured with the
